Jackson, the former Cal star, caught 82 passes for 1,332 yards and nine touchdowns last season in his sixth year with the Eagles. He is scheduled to make $10.5 million in base salary in 2014. The 49ers currently have $3.726 million in salary-cap space.

Baalke was not speaking about Jackson, but he did offer insight into the idea that the 49ers, who have lost in the postseason to the eventual Super Bowl champion in each of the past three seasons, are just “one player away.”

“I do believe you’re never one player away because too much can happen,” Baalke said. “You could acquire that player and the very next day that player gets injured and he’s done for the year. And then you’re back to square one and you have to tell yourself, ‘Well, we’re still one player away.’ I don’t buy that philosophy.”
